Why is there no DTSHD encoder available as ~2022?

This is quite irritating, except for the DTS HD Master Suite there's nothing. I'm no programmer and I've looked everywhere.

eac3to can take DTSHD and output DTSHD, that's as far as I've gotten.

What about you guys? Can we teamwork this one?

Yes, but beware of cease and desist letters.

There are better (best ratio size/time) lossless encoders, see here.

Flac, Alac, Wavpack and Tta are open source and supported in mkv container.

There is DTSHD encoders, otherwise you wouldn't have DTSHD audio tracks on Blu-Ray.
Now, if you're looking for free encoders, maybe it's because DTSHD is licensed or something like that.

I am open for all alternatives.
Minnetonka has a DTS-HD encoder for Compressor 3 (MAC).

FLAC is more than good enough for most needs.

Not only is it supported by most software media players, it's also supported my many hardware playback devices, such as: AVR's, Blu-ray disc players and TV's.

And you can always encode the audio twice and mux both versions with the video. Maybe one audio track as AAC for players that don't support your chosen lossless format, and a lossless audio track for those that do.

Does anyone know a programmer that could make something creative transcodingwise with DTSHD format?
Like FFMPEG but with encoder?
Thank you,
you are Earth's only hope.

Why do you want DTS-HD? If you want something that will pass-through to AVRs and soundbars, ffmpeg's TrueHD encoder works fine as of a couple of months ago.

I can't understand that interest about a ineficient lossless encoder.

For BD's compatibility you can use other formats and also PCM uncompressed.

TrueHD Encoder is experimental and have some rough spots. Also multichannel >2 support have no downmix and is not really tested much. I'm the only one who develops it now.

Thanks for your work on the encoder. Can you provide any tips for using the encoder to create MKVs which have good playability? I'm trying to encode some trueHD test tones with a simple static video frame, and while MPV and VLC can play them back, my standalone Oppo player (that I actually need them on) either refuses to play (2 channel trueHD) or plays without audio (5.1 channel trueHD).

"Rufuses to play" is fixed now. Same for Plex.

For Blu-ray discs, is the most efficient one (lower bitrates).

In many of my test show a bitrate ratio like this:

Code:
Size        Ratio  File 7.1
----------- ----- ----------
 81.928.230   38  Core71.thd   Source without Atmos metadata
216.505.028  100  Core71.wav   Decoded to 71
 98.373.524   45  Core71.dts   Encodec to DTS-MA
 71.615.788   33  Core71.flac  Encodec to Flac
Flac is better, but for BD you can use TrueHD instead DTS-MA.

You are not taking into account that you need to include a AC3 core for compatibility, and also the muxing overhead when in m2ts/bluray format, for some TrueHD tracks is as high has 50%, for DTS-HD is around 18%. Resulting in a DTS-HD track 30% smaller than a True HD when muxing for Blu-ray.

You are right, it's evident than I never make BD's.

Happy to greet you again SquallMX.

Is possible to remove the atmos part leaving the audio untouched?

Of course with the ffmpeg filter:

ffmpeg -i Atmos.thd -bsf:a truehd_core -c:a copy plain_thd.thd
